The Greeves Trials 20T motorcycle entry into the world of road-racing was prompted by the efforts and success of Reg Everett who, during the 1962 season had campaigned a machine built from a combination of Greeves roadster and motocross components. Successes came quickly for the new model in the hands of riders such as Everett, Joe Dunphy and Dave Simmonds which aided the machine commercially, 94 of the RCA models having been sold when production ended in May 1964 to allow the introduction of the RCB with an engine of Greeves own design and an Albion 5-speed gearbox.
